BOTTLE-CAP.

SPECIFICATION forming part of Letters Patent No. 364,334, dated June 7, 1887.

Application filed March 9, 1887. Serial No. 230.210. No modold' To aZZ whom it may concern.-

Be it known that we, PAUL H. BRINK, a subject of the Emperor of Germany, and JAMES B. AYERS, a citizen of the United States, both residents of New York city, in the county and State of New York, have invented a new and useful lm rovemcntin BottleGaps, of which the following is a spetitication.

Our invention has for its object to furnish a bottle'cap that shall be air-tight, easily opened to allow the contents of the bottle to be poured out, and quickly and securely shut or fastened when the desired quantity has been withdrawn, that will be adjustable, so as to fit the neck ofany ordinary bottlc,and can be quickly applied or removed from the same, and that will dispense with the use of corks or other stoppers for all nolrelfervescent liquids, either during their shipment or actual use. The said bottle-cap is-ornamental in appearance and efficient in use, and can be cheaply manufacvtured.

vided centrally into two equal parts, said equal parts being joined together by a spring-hinge. Said cap is also provided with a rubber lining and a spring-catch, for purposes to be hereinafter described; also, a standard to support said cap, madeintegral with an open ring that clasps the neck of bottle, the ring terminating in lugs and shoulders to limit the opening of cap, all as hereinafter described.

Figure 1 represents a perspective view of oun improved bottle-cap as it appears closed and in position on the neck of a bottle. Fig. 2 is a plan view of cap in an open position attached to a bottle. Fig. 3 is a sectional plan view on line y y of Fig. 4, showing cap closed and fastened in that position. Fig. 4 is a vertical section taken on line as 00 of Fig. 3, showing cap closed. Fig. 5 is a detail View. Fig. 6 is a view of a modified form of our cap,- parts being in section.

Similar letters of reference indicate corresponding parts in all the figures.

A represents the top part or neck of a bottle. 13 represents an open ring, terminating at either end in projecting lugs b I). Said lugs f and as represented in drawings.

2) b are provided with screw-threaded holes adapted to receive a screw, 0. This screw 0 is of some length toadmit of adjusting the ring B to the difierent-sized necks of various bottles. By loosening ort-ightening said screw 0 t-hering B will be enlarged or contracted, and thus made to tightly clasp the neck of any bottle.

A standard, 0, made integral with the ring B, rises upwardly from said ring, and has its apex formed into a pintle, D, to receive the k nu cklcs (I, attached to cap E to form ahinge, H.

Confined between the upper and lower pairs of knuckles (Z and wound around the pintle D is a coiled spring, F. The upper and lower extremities of said spring are extended sidewise in opposing directions, as shown at f and The extension f will be fastened to the inner side of one section of cap E, and extension f to the inner surface of the opposite section of cap E. Said spring F at all times has a tendency to swing each of the cap-sections outwardly and away from each other, both sections of cap E swinging on pintle l), and to uncover the mouth of bottle, as represented in Fig. 2.

Lugs g g are formed on upper portion of and integral with the standard 0, and, as shown clearly in Figs. 1 and 5 and in dotted lines in Fig. 4, receive the two lower knuckles of hinge H between them, and control the outward throw of both sections of cap E by the respective halves of cap E being brought up against said lugs g g, as shown in Fig. 2.

The cap E is a metallic shell covering the mouth of bottle and extending down upon the outside of same for half an inch or there about, and consists of two equal sections, E and E". These sections E and E are united, as before described, byaspring-hinge, H, and

a spring-catch, I, is arranged diametrically opposite, as shown best in Fig. 3.

The entire inner surface of both sections of cap E is covered with rubber, E to exclude air, dust, &c., and prevent evaporation or leakage of contents of bottle when cap is closed.

The catch I consists of a flat spring, 17, riv eted to one haltsection, E of cap E, and provided with an outwardly-projecting pin, f. This pin is beveled or rounded off on the side app'roachin g the opposite section, E, of cap E,

so as to be acted upon by opposite section, E, when the two sections E and E of cap E are brought together and pass inside the shell of section E, depressing the spring t until pin f meets hole in keeper h, when the spring 1' will force the pin f to enter hole in keeper h and lock bot-h sections firmly together, as shown best in Fig. 3. Spring i is also provided with a button, 7L2, the stem of which passes loosely through a hole formed in the meeting edges of the two sections E and E and then attached to spring i. By pushing button 72. inwardly the spring 2' will be forced back sufficiently to disengage the pin f, attached to spring i, from keeper h, and the two sections of cap E will be instantly thrown outwardly into position shown in Fig.2 by the action of the coiled spring-hinge H, uniting said sections.

- To accommodate the necessary movement of spring-catch I and to receive the same, a swell, N, is formed on each of the front meeting edges of the bottle cap-section's E and E of such dimensions as to insure the easy working of said catch 1.

The operation is as follows: When cap is closed and it is desired to use the liquid in bottle, grasp the neck of bottle and press with thumb on button h". This releases the front edges of the cap-sections E and E, and the action of the spring'hinge H upon them will cause said sections to swing outwardly and in opposite directions on pintle D until the movement of each of said sections is arrested by The name of the contents of bottle may be,

suitably engraved upon outside face of bottlecap E. v t

The ring B, with its lugs b 1), standard 0, with its lugs g g, and the blank to form the pintle D will be struck up out of one piece of thin metal and then bent to desired shape.

The sectionsE and E of cap E will be thin metal castings with the knuckles (2 formed upon them, thus reducing their cost of manufacture to a minimum.

In case of breakage the parts can be easily removed and replaced, the head of pintle D being but slightly swaged down on a washer placed on top knuckle of hinge H.

From above description it will be seen that when the cap is closed it will be impossible for air to enter bottle, or the contained liquid to evaporate or be spilled; also, that the de vice protects the contents from the entrance of dust or insects. v

When it is desirable to use ourbottlecap on bottles that vary considerably in the distance from the mouth of bottle to the commencement of neck, we make the standard 0 and open ring 13 independentof each other, and provide a block, K, fastened to ring B, with a slot in it to receive and hold the standard O and allow the standard 0 to be freely moved up or down to adjust cap E to mouth of bottle, and to be held in any such position by tightening the screw L.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- 1. The combination, with two bottle-cap seetlons formed with hinge-knuckles, of apintle by which the said sections are connected, a spring carried by the pintle and arranged to bear against the capsections. and means, substantially as described, for locking the sections together in a closed position, all as hereinbefore set forth.

2. The combination, with asectional bottlecap, of a supportingstandard to which the sections of the cap are connected and a springcatch carried by one of the sections and arranged to engage with the other section, substantially as described.

3. The combination, with a bottle-cap made in sections, of a cap-supporting standard, an

opening spring, and aspring-catch, said cat-ch being carried by one of the cap sections and arranged to engage with the other, substantially as described.

4. The combination, with two cap-sections having hingeknuckles, of a standard formed with a pintle with which said knuckles engage, a spring coiled about the pintle and engaging with the cap sections, a means for connecting the standard to the bottlc,and a springcatch carried by one of the cap sections, sub stantially as shown and described.

5. The combination, with two cap-sections having hinge-knuckles, of a standard formed with a pintle, which said knuckles engage, and with side stops, a spring coiled about the pintle and engaging with the cap-sections, a means for connecting the standard to the bottle, and a spring-catch carried by one of the cap-sections and arranged to engage with the other, substantially as described.

6. A hottlecap support consisting, essentially, of a standard, a pintle, stops at either side of pintle, and an open ring having lugs formed on its approaching ends, all said parts being integral, substantially as shown and'de scribed.

In testimony that we claim the foregoing as our invention we have signed our names, in presence of two witnesses, this 5th day of March, 1887.
